Hi,
I'm devastated and really need your help. I have to connect to a FoxPro database. I use the FoxPro-oledb driver and the following connection settings. 
Code:
<connectionStrings>
    <add name="DOCexpert.Anwenderstammdaten.Explorer.Properties.Settings.ForDBConnectionTestConnectionString"
      connectionString="Provider=vfpoledb.1;Data Source=C:\Dokumente und Einstellungen\All Users\Dokumente\Visual FoxPro Projects\ForDBConnectionTest.dbc;Collating Sequence=machine;"
      providerName="System.Data.OleDb" />
  </connectionStrings>
  <nhibernate>
    <add
      key="hibernate.connection.provider"
      value="NHibernate.Connection.DriverConnectionProvider"
    />
    <add
      key="hibernate.dialect"
      value="NHibernate.Dialect.GenericDialect, NHibernate"
    />
    <add
      key="hibernate.connection.driver_class"
      value="NHibernate.Driver.OleDbDriver, NHibernate"
    />
    <add
      key="hibernate.connection.connection_string"
      value="Provider=vfpoledb.1;Data Source=C:\Dokumente und Einstellungen\All Users\Dokumente\Visual Studio 2005\FoxProDataBase\MasterData_User.DBC; Collating Sequence=machine;"
    />
    <add 
      key="hibernate.show_sql" 
      value="true"
    />
  </nhibernate>
As dialect I also tried MSSQL2000Dialect and one which I have ported from Hibernate which is designed for FoxPro. All of the work well as long as I read and update data. Inserting data (insert into) works with none of them. Now I have no further idea what to do. Does anybody have an hint or idea how I can fully connect to the FoxPro Tables. If I do not get that to work, I'm in deep trouble. Can anybody help me please!!!! 
Thank you in advance for all your efforts and feedback antoschka
